System.Timers cross platform issue WP8

I wrote a working project which used System.Timers class. This worked fine on Windows, but when I did a build for Windows Phone, I got a build error saying System.Timers was not found in the framework.

Reference Rewriter: Error: type `System.Timers.Timer` doesn't exist in target framework. It is referenced from Assembly-CSharp.dll at System.Void codebehind::Update().
UnityEngine.Debug:LogError(Object)

MSDN shows System.Timers, but typically Windows devices prefer System.Threading to use DispatcherTimer class. In any case, I need a timers class which will work in the Windows phone. What can I use.

 

Looking at the compatability list, it looks like System.Threading.Timer is better. However, I would be apprehensive about using .NET level functionality for this. From the docs: The method does not execute on the thread that created the timer; it executes on a ThreadPool thread supplied by the system.

You cannot execute any Unity functionality from the non-gameplay thread. Instead, you're probably better off using Unity's Invoke / InvokeRepeating.

 

You can use Invoke(methodName, timeInSeconds) instead of timers (also InvokeRepeating(methodName, timeInSeconds, timeBetweenInvokes).

 

Yes Jodon, System.Threading.Timers is closer to a real solution, thanks. The problem is that Unity3D does not have a System.Timer code class that is compatible with the Windows Phone. That's a cross-compatibility issue which is going to hurt a lot of apps that rely on it.

The idea of writing my own timer class by hand and choking out the already sluggish main loop, when there are perfectly good feature rich event driven timer classes that have been around since the stone age is not my idea of a good time.

I ended up wrapping System.Threading.Timers in a 'looks like' class, and added the delegate hooks so the graphical thread get its slow non-atomic, updates. It builds to the Windows Phone successfully.

 

Hi. I am also trying the same solution but nothing worked me so far. Can you please share the wrapper you are using. Thanks in advance
